Brief Summary

The quantification of the strength-producing capacity of the knee joint muscles by isokinetic measurement is one of the most widely used tools for monitoring and deciding whether to return to sport after ACL reconstruction. However, the isokinetic evaluation performed in current practice does not exploit all the measures offered by this exploration technique, which can lead to errors in analysis and interpretation of the results and underestimate its ability to predict a return to sport under optimal conditions. Recently, more complete analysis models than those currently in use and integrating the moment-angle relationship have thus proposed the use of functional ratios sweeping the whole amplitude of the knee joint. Baumgart proposed an analysis of the variation of isokinetic force moments at each angle after ligamentoplasty. This approach seems to be the future of isokinetic performance analyses, but for the moment this has only been used in pathological populations and on small numbers of patients (less than 40). There are therefore no reference values in healthy subjects.

Outcome Measures

Primary Outcomes (1)

• Distribution of knee isokinetic angle

  The primary outcome will be composed of the following elements:(1)- a curve representing the distribution of the mean (and confidence interval) of the normative values of the knee flexors/extensors ratio at each angle on the tested amplitude, (2) a curve representing the distribution of the mean (and confidence interval) of the normative values of the right/left ratio at each angle on the tested amplitude,(3) a curve representing the distribution of the mean (and confidence interval) of the normative values of peak torque (normalized by subject mass) produced by the flexors and extensors at each angle over the amplitude tested, (4)- the distribution of the mean (and confidence interval) of the right/left differential on the value of the peak torque on the flexors and extensors and its angle of occurrence.

Study Arms (1)

Healthy subjects

OTHER

Evaluation carried out on a BIODEX S4 Pro isokinetic dynamometer after a standardised 10-minute warm-up on this same dynamometer . The measurement range will be from 0° (full extension) to 90° of flexion for each knee, providing 91 degrees of measurement.

Other: Evaluation of the strength of knee flexors and extensors

Interventions

Evaluation of the strength of knee flexors and extensors OTHER

Each participant will benefit from a clinical evaluation and an evaluation of the strength of knee flexors and extensors using an isokinetic dynamometer after a 10-minute warm up.
